Donzi 18 Classic 2006 vs Donzi 22 Classic 2006 — Same Brand, Different Boat

The Donzi 18 Classic 2006 vs Donzi 22 Classic 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Donzi 22 Classic 2006 measures 22,0 feet overall (2006), giving it roughly 4,0 additional feet of deck space compared to the Donzi 18 Classic 2006 at 18,0 feet (2006). At 27 lbs and 34 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 470 hp, the Donzi 22 Classic 2006 has a 120-hp advantage over the Donzi 18 Classic 2006's 350-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Donzi 22 Classic 2006 carries 52 gallons versus 41 gallons in the Donzi 18 Classic 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Donzi 22 Classic 2006 is rated for 6 passengers, while the Donzi 18 Classic 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 22 Classic 2006 could be the deciding factor.

Bottom line: Choose the Donzi 22 Classic 2006 if your priority is putting more people on the water — it handles 6 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Donzi 18 Classic 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Donzi 18 Classic 2006 vs Donzi 22 Classic 2006 — Common Questions

Which is the larger boat — the Donzi 18 Classic 2006 or the Donzi 22 Classic 2006?
The Donzi 22 Classic 2006 is the longer of the two at 22,0 feet overall. The Donzi 18 Classic 2006 comes in at 18,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Donzi 18 Classic 2006 or the Donzi 22 Classic 2006?
For trailering, the Donzi 18 Classic 2006 has the edge at 27 lbs dry weight versus 34 lbs for the Donzi 22 Classic 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Donzi 22 Classic 2006 is rated to a maximum of 470 hp, giving it the larger power ceiling. The Donzi 18 Classic 2006 tops out at 350 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Donzi 18 Classic 2006 is Coast Guard rated for 5 passengers, while the Donzi 22 Classic 2006 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Donzi 18 Classic 2006 and Donzi 22 Classic 2006 share an 7 ft. 0 in. (3.13 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Donzi 18 Classic 2006 or the Donzi 22 Classic 2006?
The Donzi 22 Classic 2006 has the bigger tank at 52 gallons, versus 41 gallons on the Donzi 18 Classic 2006. That 11-gallon difference translates to roughly 33–55 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Donzi 18 Classic 2006 and Donzi 22 Classic 2006 from the same manufacturer?
Yes — both the Donzi 18 Classic 2006 and the Donzi 22 Classic 2006 are built by Donzi. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
